An arrangement of position transmitters on a selector rod for automatic speed change transmissions in motor vehicles, which interact with housing-mounted position sensors of an electrical speed detection circuit, at least one selector rod on its end regions being movably supported in cross walls of the housing of the transmissions and being actuated by means of a preferably electrohydraulically controlled speed selection unit where the selector rod projects through a through an opening in a cross wall of the transmission, which wall separates the oil compartment into the gear chamber which holds at least the speed selection unit and the position sensors, and the position transmitters are attached directly to the selector rod such that the selector rod with the position transmitters can be mounted through the through the opening as a mounting unit.

The arrangement according to claim wherein said position transmitters are disposed between end-side connecting means of the selector rod on the speed selection unit and the cross wall.
The arrangement according to claim wherein said selector rod is made preferably rectangular in cross section, and that the position transmitters are made on a narrow side of the selector rod.
A position sensing assembly for a speed changing transmission having a housing defining a compartment provided with a speed selector unit, and an opening communicating with said compartment, and a rod displaceable along the length thereof received through said opening and operatively connected at an inserted end thereof with said speed selector unit, comprising;
